United States Patent 9 RESILIENT COVER FOR VISE JAW John J. Linskey and Eugene H. Call, Akron, Ghio Application June 2, 1954, Serial No. 433,885

2 Claims. (Cl. 81-38) This invention relates to vises and in particular, relates to detachable face plates for application over the conventional jaws of a vise.

In the conventional use of vises to perform the function of work holding, it is often found expedient to provide the work-gripping surfaces of the vise with a material that is softer than the metal normally employed in such vise jaws. In the past this has been done primarily for the purpose of preventing marring of an article that is to be gripped by these jaws. For example, it is normally undesirable to hold articles of wood in the ordinary vise jaws, in view of the fact that the serrated or otherwise roughened surfaces of the vise jaw transfer their configuration to the article being supported because of the hardness and inflexibility of the same with respect to the wooden article being held.

To obviate this difliculty, in the past several covering devices for the face plates of the vise jaw have been provided. Without exception these prior art devices have been rendered commercially unfeasible by virtue of their complicated, and accordingly expensive, construction. Another disadvantage of the prior art devices is their inadaptability to be received over vise jaws of varying height. In the main, these prior art devices are hung or otherwise suspended with respect to the vise jaw with the result that the same are invariably incapable of accurately holding work that is to be positioned between the vise jaws.

Accordingly, it is one object of this invention to provide a resilient covering for the ace plate of a vise jaw that is of simplified one-piece construction and has means thereon for firmly securing the same to said vise jaw.

It is another object of this invention to provide a resilient vise-jaw covering that is receivable over a plurality of vise jaws of varying height and construction.

It is a still further object of this invention to provide a resilient vise-jaw covering that is attached to a conventional vise jaw in secure and aligned relationship therewith.

These and other objects of the invention will become more apparent upon the reading of the following brief specification considered in the light of the accompanying drawings.

Of the drawings:

Figure 1 is a perspective illustration of the improved resilient vise jaw covering.

Figure 2 is a cross-sectional elevation of the resilient vise jaw covering.

Figure 3 is an end view showing a pair of resilient visejaw covers applied over the jaws of a vise.

Figure 4 is a cross-sectional elevation of a modified form of the invention.

Referring now to the drawings and in particular to Figure 3 thereof, an improved resilient covering for a vise jaw, generally designated as 10, is shown positioned about work-engaging faces 11c, 110 of vise jaws 12, 12, so as to be operably movable therewith in a manner to be described.

ice

With particular reference now to the construction of the resilient covering 10, the same is shown as being of one-piece construction, including a base portion 20, that is defined by a work-engaging surface 21, and a surface 22 that is spaced with respect thereto and is normally engageable with the usual facellc, of the vise jaw 12.

For the purpose of securing the base portion 20, with respect to the face 11c of the vise jaw 12, the base portion 20 is shown provided with a pair of flanged extensions 23 and 24, that extend away from the surface 22 for subsequent tensional engagement with top and bottom surfaces 11a, 11b, respectively, of the jaw 12, in a manner to be described.

To this end, the flange 23 is shown in Figure 2 as being of somewhat tapered cross-sectional configuration and is further illustrated as extending from the base portion 20 at an angle somewhat less than 90, the arrangement being such that the unstressed angle between the surface 22 of the base portion and a surface 23a of the flange member is shown in Figure 2 as approximating 75", although it is apparent that this angle can be varied considerably as long as the same remains acute, whereby the flange 23-can be distorted upon application against the jaw 12, which normally has the faces 11a and 110 disposed at right angles.

The remaining longitudinal surface of the flange 23, is shown defined by adjoining surfaces 23b, 23c, the latter of which is joined with a surface 21a to present a straight edge 25, that extends longitudinally of the jaw covering 10. This latter surface, 21a, is shown in Figure 2 as being defined by a plane that is disposed at an acute angle to the plane of the work-engaging surface 21, this arrangement being made to permit the straight edge 25 and the surface 21a to move into the plane of the surface 21, upon deflection of the flange 23, as shown in Figure 3.

For the purpose of securing the vise-jaw covering 10, with respect to both the top and bottom surfaces 11a, 11b, respectively of the jaw 12, the surface 22 is shown terminating adjacent to an inclined surface 26, one edge of which is defined by a resilient flange member 24 of arcuate cross-sectional configuration that extends longitudinally of the vise-jaw covering 10. By virtue of its relatively reduced thickness and its arcuate curled configuration, a free edge portion of flange 24, when in its unfiexed condition, is directed towards the longitudinally extending surface 22. In this manner, either said free end or an inner face 24a of the resilient flange 24, depending upon the height of the vise jaw 12, is engageable with the bottom surface 11b of the jaw 12, as is best shown in Figure 3 of the drawings.

In use or operation of the improved resilient vise-jaw covering 10, the same is first positioned longitudinally with respect to the face of the vise jaw 12. In this position, the top flange 23 is positioned over the surface 11a of the jaw 12 and the body portion 20 is moved downwardly to distort the flange 23 to the position of Figure 3. At this point the resilient arcuate flange 24 is easily flexed outwardly from the surface 22 until the same longitudinally overlies surface 11b at which time the arcuate flange 24 may be released. At this time the vise-jaw covering 10 is fully positioned with respect to the jaw 12, and it will be noted that the distortion of the flange 23, has automatically operated to move the straight edge 25 within the plane of the workengaging surfaces 21, and accordingly the surface 21 will be aligned with the surface 11c in approximately parallel relationship, due to the aforementioned clamping action that is etfectuated by the resiliency of the flanges 23 and 24.

From the foregoing, it is apparent that if the dimension between" the surfaces 11:: and 11b were increased the arcuate configuration of the resilient flange 24 would still operate to firmly engage both the top and bottom surfaces, 11a and 11b.

It will be seen from the foreg ing-thatthere hasbeen provided a new and novel; resilient vise-jaw covering that features the positive attachment of aresilient'work-engaging surface over the conventional vise jaws. This attachment is etfectuated'through the medium of separate'and distinctly constructed flanges that are engageable with surfaces of varying heights, in view of their specific configurations and inherent recovery properties,-;to secure this novel covering in perfectlyaligned relationship.

-In"Eigure 40f the drawings there is shown ajmodified form'of the invention designed for application'to a conventional-face'plate of a wood-workingvise (notshown). Inthis modified form of'the invention, a substantially rectangular sheet 30, of resilient materialis provided, the same having a work engaging suffacefill, as well as a second spaced surfaceGZ, that normally engagesthe workenga'ging surface of the conventionaljaw of 'a' vyoo dworking vise (not shown). Extendingperpendicularly fromyone longitudinaljedgeof the sheet 'j30, is shown a resilient flange member 33, th at-has-an exterior surface 34,; one longitudinal edge of 'whichdefines asurface 35, theplane of which is inclined with respect to the plane of the 'surface 34. As'shown in Eigure4, a longitudinai side of the'flange '33; that is disposed opposite-to-theiside which joins sheet 30,is defined by a second resilient flange 36, that is presented in a plane that is acute-to'the plane: ofthe' flange 133. V

' In 'usingthe modified form of the ,inventionthe flange 36 -is first hooked over the rear OfIhC jaw of the conventional wood-working vise and in-this-ppsition the flange 33, together with, the'sheet 30, is then positioned against the'top, and front (or work-engaging surface) of the -wqod-workingv ise. By reason of this lastrnentioned positioning the flange 36'will be distorted into an approximate parallel relationship'with the sheet and the workengaging surface 31. Asthe result of this deflection the plane of the surface will also be distorted until the sameis' approximately in the plane of the surface 34.

*Duringthe'timethatthe modified vise-jaw covering is positioned with respect tothe vise jaw, it is apparent that the" flange 36, by virtue of-its inherent recovery properties,'v vill be consequently urged towards the position of Figure 4 and-thus a'clamping action willibe'exerted to prevent shifting of the vise-jaw covering with respect to a vise-jaw in abuttingwrelationship thereto; a resilient flange, tapering outwardly in cross-sectional configuration at an acute angle from said surface adjacent one edge portion thereof; a second resilient flange extending outwardlytrom an opposed edge portion of saidsurface; said tapered resilient flange including an outer surface and an inner surface engageable over aportion of a vise-jaw; said outer surface being defined by a plurality of adjoining, longitudinally extending planar "surfaces,

, one of which is shiftable into substantially perpendicular relationship with respect to, said first-mentioned longitudinally extending surface upon placement of'said covering over a vise-jaw.

,2; A vise-jaw covering of the-character described, comprising; a resilient base/portion having a'longitudinally extending surface thereof positionable against a face, of a visejaw; a resilient flange extending outwardly'at an acute angle from said surface adjacent one'edge portion thereof; a'second resilient flangeextending outwardly from an opposed edge portion of said surface; said second-named flange being of arcuate reduced cross-sectional configurasaid covering can be selectively applied to vise-jaws which may' vary in height over a wide range.
